Characterization of X80 and X100 Microalloyed Pipeline Steel Using Quantitative X-ray Diffraction
Metallurgical and Materials Transactions B, 2018 Quantitative X-ray diffraction characterization of four (4) X80 and three (3) X100 microalloyed steels was undertaken. The effect of through thickness position, processing parameters and composition on the measured crystallite size, microstrain and J index (relative magnitude of crystallographic texture) was determined.

Corrosion behavior of pipeline steel transporting diluted bitumen
, 2020 An insufficient understanding of the corrosion, especially the internal corrosion, of diluted bitumen (referred to as “dilbit”) pipelines exacerbates the debate around new pipeline construction. This thesis elucidates the effects of important parameters,
